摘 要: | 对1987年5月福建南平库蚊上的虫霉流行病进行观察和鉴定,结果表明库蚊虫霉(Entomophthora culicis)是流行病的主要病原菌(92.4%),其次为弯孢虫疫霉(Eryniacurvispora)(2.9%),同时在库蚊的个体上存在着这两种虫霉的复合感染(4.7%)。库蚊虫霉分生孢子钟罩形,基部平截,端部尖突。分生孢子10.3×13.3-6.6×11.6μm,平均12.1±0.15×9.0±0.15μm,长径比1.40—1.75。休眠孢子内生或外生,平均27.1±0.14μm。假根粗大,无固着器,囊状体缺乏。在蛋黄培养基上生长微弱。对不同因子影响分生孢子萌发进行了初步的研究。

Abstract: | A large scale of epizootic occurred on Culex sp.population in Nanping of Fujian Province in May,1987.The pathogenes were Entomophthora culicis (92.4%) and Erynia curvispora (2.9%),and a small portion of Culex sp.were attacked simultaneously by these two fungi (4.7%).The conidia of E.culicis are campanulate,10.3×13.3—6.6×11.6 μm (averaging 12.1±0.15×9.0±0.15μm),L/D ratio 1.4—1.75.Resting spores globose,smooth, averaging 27.15±0.14 μm,endogenic or exogenic.Rhizoids present without differentiated hold- fasts.Cystidia absent.Growing slowly on Egg-yolk medium. |
